3,000 fps if it's a very fast barrel, but count on about 2,950. that answers your origional question, now some opinion
i can tell you, for a fact, 2,982fps with the 300smk, at 3,200 feet, will land predictably at over 2k..... why did you want or need it to do 3,200 fps? i can also tell you, that combo will break a deer at 1,589 yards...
numbers are cool, but accuracy kills, or wins, dependeing on the sport. i once, when i was new
, thought speed was everything too. i managed to get into the 700 yard club back then, with a long tubed 30-378. and then
, it hit me, i have to crank these knobs on every shot past 400 yards anyway, hmmmmm....
do as you wish, but i think you would be quite happy with a 338 lap imp., the brass is top notch and lasts forever(ish).
good luck with whatever you pick,
